Hazard analysis of Miamisburg Park Improvement Project

The City of Miamisburg plans to modify two existing small ponds just west of Mound Laboratory in the Community Park. The north pond will be deepened and made into a solar energy pond to heat a bath house and swimming pool, and the south pond will be deepened and made into a fishing pond. Because the sediment in both ponds contains small amounts of plutonium and will be moved during the modifications, this work has been reviewed for potential health and safety impacts. This analysis covered the health and safety of the public on a long-term basis and of the workers involved in the short-term modifications. The doses to man, both long and short term, were calculated for all routes of entry into the body including inhalation, ingestion, and absorption where applicable. In the preparation of this analysis, very conservative assumptions were utilized. The conclusion in all cases was the same: the potential radiation exposures represent no significant risk to the health and safety of the construction workers or the park visitors. The improvements to be made in the park involve mixing and dilution of the existing sediments with other soils, providing further reductions in the calculated radiation doses to man. The City of Miamisburg can proceed with the improvements to the park, as planned, resulting in no short-term or long-term hazard to the citizens of Miamisburg
